SPRINGFIELD, Ill. ? A police sergeant accused of raping four women since 2002 was charged in a grand jury indictment unsealed Thursday with 35 counts, including multiple attacks on three of the victims.

Sgt. Jeff Pelo, 41, had already pleaded not guilty to sexually assaulting the four women. His attorney, Steve Skelton, said he would also plead not guilty to the additional charges in the indictment.

Skelton has called the prosecution’s case flimsy. Pelo, jailed on more than $2 million bond, is scheduled to be arraigned today.

Pelo was first arrested in June and charged with attempting to break into a woman’s home in the middle of the night. At the time, he was wearing a black T-shirt and shorts and told an officer he was out looking for a home for his mother-in-law, officials said.

Police have said they found a mask, pry bar and other items in Pelo’s home that appeared to have been used in at least one of the assaults. Prosecutors said three of the accusers identified him from photo lineups and two identified him by voice.
